Abstract

An antenna with a double reflector comprising a main reflector and a sub-reflector located in opposition to the main reflector on the same axis and which reflects the electromagnetic wave coming from the energy source towards the main reflector, characterized in that there are screens (5) to along a portion of the edge of the reflector (2).
